Why Lab-Grown Diamonds Don’t Look Fake?

The rise of lab-grown diamonds has disrupted the traditional diamond industry, offering consumers a more ethical and sustainable alternative. However, despite their identical chemical and physical properties to mined diamonds, a lingering misconception persists: Why do lab-grown diamonds look fake?


Understanding the Identical Nature of Lab-Grown Diamonds

The question “Why do lab-grown diamonds look fake?” stems from a misunderstanding of their fundamental nature. Lab-grown diamonds are not imitations or simulants like cubic zirconia or moissanite. They are real diamonds, possessing the same chemical composition (pure carbon) and physical properties (hardness, brilliance, fire) as diamonds formed deep within the Earth.


The only difference lies in their origin. Mined diamonds are formed over millions of years under immense pressure and heat within the Earth’s mantle. Lab-grown diamonds, on the other hand, are created in controlled laboratory environments that replicate these conditions, accelerating the diamond-growing process to a matter of weeks or months.

Examining the Factors Contributing to the “Fake” Perception

Despite their identical nature, several factors contribute to the misconception that lab-grown diamonds look fake:

1. Lack of awareness: Many consumers are still unfamiliar with lab-grown diamonds and mistakenly associate them with diamond simulants, which are visually similar but lack the true properties of diamonds.

2. Misinformation: Some traditional jewelers, threatened by the disruption of the lab-grown diamond market, may spread misinformation about their quality and authenticity, perpetuating the “fake” perception.

3. Price difference: Lab-grown diamonds are typically more affordable than mined diamonds due to the shorter supply chain and reduced environmental impact. This price difference can lead some to believe they are of inferior quality or “not real.”

4. Visual perception: While chemically and physically identical, some lab-grown diamonds may exhibit subtle visual differences compared to mined diamonds. These differences, often related to the growth process, can be misinterpreted as signs of being “fake.”

Addressing the Visual Differences

It’s important to acknowledge that certain visual characteristics can differ between lab-grown and mined diamonds. However, these differences are not indicative of being fake and often require expert gemological examination to identify.

Some lab-grown diamonds may exhibit:

Color variations: While most lab-grown diamonds are colorless or near-colorless, some may have a slight brown or yellow tint due to trace elements present during the growth process.

Inclusions: Similar to mined diamonds, lab-grown diamonds can have inclusions, tiny imperfections within the crystal structure. However, the type and distribution of inclusions can differ, and some lab-grown diamonds may have fewer inclusions than their mined counterparts.

Fluorescence: Lab-grown diamonds can exhibit fluorescence under ultraviolet light, similar to some mined diamonds. The intensity and color of fluorescence can vary, but it does not affect the diamond’s authenticity or beauty.

It’s crucial to note that these visual differences are not universal to all lab-grown diamonds. Many are visually indistinguishable from mined diamonds, even to trained gemologists. Additionally, advancements in technology are continuously improving the quality and visual characteristics of lab-grown diamonds.

Recognizing the Value and Authenticity of Lab-Grown Diamonds

Lab-grown diamonds are real diamonds in every sense, offering the same brilliance, beauty, and durability as mined diamonds. Their ethical and sustainable production process makes them a responsible choice for consumers concerned about the environmental and social impact of mined diamonds.

When considering a diamond purchase, it’s important to educate yourself about lab-grown diamonds and dispel any misconceptions about their authenticity. Seek reputable jewelers who offer both lab-grown and mined diamonds and can provide transparent information about their origin and quality.


The choice between a lab-grown and a mined diamond is a personal one. However, understanding that lab-grown diamonds are not fake empowers you to make an informed decision based on your values and preferences.

By choosing a lab-grown diamond, you can embrace a beautiful and ethical gemstone that reflects your commitment to sustainability and responsible sourcing, without compromising on quality or brilliance.
